IUBMB Comments
Chitin oligosaccharide deacetylase is a key enzyme in the chitin catabolic cascade of chitinolytic Vibrio strains. Besides being a nutrient, the heterodisaccharide product 4-O-(N-acetyl-beta-D-glucosaminyl)-D-glucosamine is a unique inducer of chitinase production in Vibrio parahemolyticus . In contrast to EC (chitin deacetylase) this enzyme is specific for the chitin disaccharide [1,3]. It also deacetylates the chitin trisaccharide with lower efficiency . No activity with higher polymers of GlcNAc [1,3].
